PIN-ATTACHED SNAP Application filed January 15, 1921. Serial No. earner.

to the garment and is .an improvement on our snap fastener set forth in Patent #1351918 of November 2nd, 1920.

One of the principal objects of the inven tion is to make the device smaller and more compact.

Another object is to produce a device of this nature which shall be simple of construction, cheap to manufacture, and highly efhcient for the purpose for which it is desip'ned.

With these and other objects in view, the essential features of which are hereinafter fully described, are particularly pointed out in the appended clalms, and are illustrated in the accompanying drawing, in which Figure 1 is an enlarged perspective view of the male element of one form of our invention.

Figure 2 is a similar view of the corresponding female element.

Figure 3 is a horizontal sectional view of the members in fastened position.

Figure is a view showing the manner of attaching the pins to the material.

Figure 5 is a plan view of the female member in another form of the invention.

Figure 6 is a similar view of a third form of. the invention.

Figure 7 is a similar view form of the invention.

Like characters of reference refer to like parts in all views.

This invention contemplates the producino: of a snap fastener, the male and female members of which may be respectively provided with pins for securing them to the materials which they are to fasten together and the female member being provided with a spring member or members, either on the pin or otherwise, for co-acting withthe exof a fourth trusion on the male member forsecuring the same in closed condition. Referring to the drawing more in detail. and in particular to ll "ures 1 to 10 represents the malc'membor of our i iproved snap fastener and 11 rep ents the female member, both of r .mhers being flat plates having a bearing is rolled up at one end thereof. in each b ring 12 is pivotallv seated the bight of a 1 shaped pin or securing element 13, the lop f which tend to spring outwardly. The tree pointed ends of the pins ar adapted to be received by respective curled over ears'l i which form sheaths or protectors pi venting; catching of the points on the material bands.

Rising from the face or the male member is the stud 1d which may or may not be slotted crosswise as at 15, and which is undercut at 16 lengthwise of the member 10 either on one or on both sides as desired. Mounted on the pin side of the female member 11 and surrounding the aperture 1'? therein is a low collar 18 provided with slots 19 into which the legs of the pin of the female member 11 project when the pin is in closed condition.

It will be readily understood that when the parts are in co-acting position the legs of the pin on the female member will ex-.

tend through the slots 19 in the collar 18 and into the slots 16. if a single leg pin is used instead of the double leg pin, of course only one slot 19 and one slot 16 will be provided. The pins are springy enough to permit the proper snapping and opening 01 the fastener, but are strong enough to withstand a reasonable amount of strain so as v therefrom through a slot 9 3 in the collar 18.

The slots19 are dispensed with, and only one slot 16 is provided to CO-fiCt with the wire In theform shown in ture is similar to that in l l ure 6 but the Figure 7, the strum spring member 24 goes entirely around the collar 18 and extends mto the two slots 18 therem.

While we have described what we deem to v be themost desirable embodiments of our invention, it is obvious that the same is susceptible of embodiment in many forms without departing from the spirit of our invention; and we therefore, do not limit our-v selves to the exact details herein set forth nor to anything less than the whole of our invention limited only by the appended claims.

lVhat is claimed is 1. A fastening dev1ce comprlsing a member having a socket and a slotted collar surrounding said socket, a second member havcollar for co-actinp with said stud as and for the purpose set forth.

2. A fastening device comprising a member having a socket and a slotted collar surrounding said socket, a second member having a stud slotted in at its sides and adapted toenter said socket and collar, and a pin pivoted on said socket member and a clothpiercing portion of which is adapted to extend through the slots in said collar and into the slots in said stud to secure the two members together. i

3. A fastening device comprising a male member havinglugs and a stud under cut at opposite sides,- a female member formed with lugs and a socket and a collar surrounding said socket and undercut at opposite sides to correspond with said stud, and a pair of U shaped pins each pivoted at its bight to one end of a respective one of said members and engageable at its freeends with said lugs, the pin of said female member being projected into the undercuts of said members when its free. ends are co-operative with its lugs, the lugs'forcing the pin into said undercuts, and said collar forcing the pin into engagement with its lugs.

In testimony whereof we have afiixed our signatures.
